Which ORMs are supported by this skill?

This skill provides specific syntax, patterns, and best practices for major Node.js ORMs including Sequelize, TypeORM, and Prisma.

How does it handle zero-downtime migrations?

It utilizes multi-phase strategies such as adding backward-compatible columns, backfilling data, and code-switching to ensure service remains uninterrupted during schema changes.

Can it assist with data transformation between different databases?

Yes, it includes patterns for complex data transformations, such as splitting combined strings into distinct columns or handling dialect differences between PostgreSQL and MySQL.

What is the recommended approach for failed migrations?

The skill emphasizes transaction-based migrations and mandatory rollback (down) methods to ensure the database can be safely reverted to its previous state if an error occurs.
